The double florin (4/-)[1] was one of the shortest-lived British coin denominations ever, only being produced during four mint years, between 1887 and 1890. The silver coin weighed 22.6 grams (0.80 oz) and was 36 millimetres (1.4 in) in diameter.

The obverse side of the coin shows a portrait of Queen Victoria wearing the Jubilee Crown, with the inscription "VICTORIA - DEI GRATIA" (Victoria - By the grace of God), while the reverse side shows four cruciform-crowned shields bearing the emblems of England (x2), Scotland, and Ireland, with sceptres between the shields, in the style of Charles II's gold coins designed by John Roettiers; the inscription on the reverse reads, "FID DEF BRITT REG date".

The coin was introduced as part of a short-lived attempt at decimalization of the currency, after an earlier attempt had spawned the florin. As with the sixpence, Shilling, and Florin the coin was not demonetized as part of the 1971 decimalization. Unlike those coins it has not been subsequently called in, and it remains legal tender for 20 pence. The coins are not likely spent, though, as the silver content of each coin is worth far more than 20 pence.

The coin acquired the nickname of "Barmaid's Grief" due to its similarity to the slightly larger crown coin (worth 5 shillings, 25% more than the double florin), as neither coin was marked with its denomination and both used an identical portrait of Queen Victoria on the obverse.[2]

Some coins minted in 1887 (the first year) had a Roman 'I' instead of an Arabic '1' in the date. This went unnoticed for a time until corrected, allowing the balance of the mint run to be produced with the correct date. These two variations are worth approximately the same, making the series more interesting for collectors.[3] Some coins dated 1888 and 1889 have an inverted Arabic 1 instead of the second I in VICTORIA as the result of a broken punch.

Coins of the pound sterling

The standard circulating coinage of the United Kingdom is denominated in pounds sterling, and, since the introduction of the two-pound coin in 1994, ranges in value from one penny to two pounds. Since decimalisation, on 15 February 1971, the pound has been divided into 100 (new) pence. From the 16th century until decimalisation, the pound was divided into 20 shillings, each of 12 (old) pence. British coins are minted by the Royal Mint in Llantrisant, Wales. The Royal Mint also commissions the coins' designs.

Fifty pence (British coin)

The British decimal fifty pence (50p) coin – often pronounced fifty pee – is a unit of currency equalling one half of a pound sterling. It is a seven-sided coin formed as an equilateral-curve heptagon, or Reuleaux polygon, a curve of constant width, meaning that the diameter is constant across any bisection. Its obverse has featured the profile of Queen Elizabeth II since the coin’s introduction in 1969. Four different portraits of the Queen have been used, with the latest design by Jody Clark being introduced in 2015. The second and current reverse, featuring a segment of the Royal Shield, was introduced in 2008.

Five pence (British coin)

The British decimal five pence (5p) coin – often pronounced five pee – is a unit of currency equaling five one-hundredths of a pound sterling. Its obverse has featured the profile of Queen Elizabeth II since the coin’s introduction on 23 April 1968, replacing the shilling in preparation for decimalisation in 1971. A smaller version of the coin was introduced in June 1990 with the older coins being withdrawn on 31 December 1990. Four different portraits of the Queen have been used, with the latest design by Jody Clark being introduced in 2015. The second and current reverse, featuring a segment of the Royal Shield, was introduced in 2008.

Half farthing

The British half farthing coin, usually simply known as a half farthing, was a unit of currency equaling 1/1,920 of a pound sterling, or one eighth of a penny. It was minted in copper for use in Ceylon, but in 1842 they were declared legal tender in the United Kingdom. Two different obverses were used. Like all British coinage, it bore the portrait of the monarch on the obverse.

Florin (British coin)

The British florin, or two shilling coin, was issued from 1849 until 1967, with a final issue for collectors dated 1970. Valued at one tenth of a pound, it was the last coin circulating immediately prior to decimalisation to be demonetised, in 1993, having for a quarter of a century circulated alongside the ten pence piece, identical in specifications and value.

Halfpenny (British pre-decimal coin)

The British pre-decimal halfpenny coin, usually simply known as a halfpenny, historically occasionally also as the obol, was a unit of currency that equalled half of a penny or ​1⁄480 of a pound sterling. Originally the halfpenny was minted in copper, but after 1860 it was minted in bronze. It ceased to be legal tender in 1969, in the run-up to decimalisation. The halfpenny featured two different designs on its reverse during its years in circulation. From 1672 until 1936 the image of Britannia appeared on the reverse, and from 1937 onwards the image of the Golden Hind appeared. Like all British coinage, it bore the portrait of the monarch on the obverse.

Farthing (British coin)

The British farthing coin, from "fourthing", was a unit of currency of one quarter of a penny, or ​1⁄960 of a pound sterling. It was minted in bronze, and replaced the earlier copper farthings. It was used during the reign of six monarchs: Victoria, Edward VII, George V, Edward VIII, George VI and Elizabeth II, ceasing to be legal tender in 1960. It featured two different designs on its reverse during its 100 years in circulation: from 1860 until 1936, the image of Britannia; and from 1937 onwards, the image of a wren. Like all British coinage, it bore the portrait of the monarch on the obverse.

Threepence (British coin)

The British threepence (3d) coin, usually simply known as a threepence or threepenny bit, was a unit of currency equaling one eightieth of a pound sterling, or three old pence sterling. It was used in the United Kingdom, and earlier in Great Britain and England. Similar denominations were later used throughout the British Empire, notably in Australia, New Zealand, and South Africa.

Two guineas (British coin)

What is nowadays known as the Two Guineas coin was first minted in 1664, in England, when it had a nominal value of forty shillings and it was known as a forty-shilling piece, then it was later called a double-guinea or two guinea piece, worth forty-two shillings after the Proclamation of 1717 finally settled the value of a guinea. The term "guinea" indicates the source of the gold used to strike the coin, i.e. from west Africa. For most of its period of production the coin weighed 16.7 - 16.8 grams and was 31-32 millimetres in diameter, although the coins of Charles II were about 0.1 grams lighter and 1 millimetre smaller.

Sixpence (British coin)

The sixpence, sometimes known as a tanner or sixpenny bit, is a coin that was worth one-fortieth of a pound sterling, or six pence. It was first minted in the reign of Edward VI and circulated until 1980. Following decimalisation in 1971 it had a value of ​21⁄2 new pence. The coin was made from silver from its introduction in 1551 to 1947, and thereafter in cupronickel.

Shilling (British coin)

The shilling (1/-) was a coin worth one twentieth of a pound sterling, or twelve pence. It was first minted in the reign of Henry VII as the testoon, and became known as the shilling from the Old English scilling, sometime in the mid-sixteenth century, circulating until 1990. The word bob was sometimes used for a monetary value of several shillings, e.g. "ten bob note". Following decimalisation on 15 February 1971 the coin had a value of five new pence. It was made from silver from its introduction in or around 1503 until 1947, and thereafter in cupronickel.

Penny (British pre-decimal coin)

The pre-decimal penny (1d) was a coin worth 1/240 of a pound sterling. Its symbol was d, from the Roman denarius. It was a continuation of the earlier English penny, and in Scotland it had the same monetary value as one pre-1707 Scottish shilling. The penny was originally minted in silver, but from the late 18th century it was minted in copper, and then after 1860 in bronze.

Twopence (British pre-decimal coin)

The pre-decimal twopence (2d) was a coin worth one one-hundred-and-twentieth of a pound sterling, or two pence. It was a short-lived denomination, only being minted in 1797 by Matthew Boulton's Soho Mint.
